Know what your feeling I've lost a lot of family from medical reasons and friends from this war. Keep in touch with family, let yourself cry. I most recently lost my uncle and I still have a hard time with it, I visit his grave and just talk to him to ease my mind. Time will help you heal, along with the thought of even though they are not physically there any more they are always with you. In memories of what yall did together, and that alone will keep them alive and with you.
Glad I could help. Hope the healing process can begin for you quickly
at first there is shock and denial but in time u will come to accept that death has occured and there is nothing that can be done then the healing starts
